<title>CSS Pseudo-Elements Test: paired cascade: UA default highlight colors are used when highlight pseudo cascade yields only properties other than highlight colors</title>

<meta name="assert" value="This test verifies that setting text-decoration on ::selection does not suppress any UA non-initial used values for color or background-color. While the former is an applicable (shorthand) property for highlight styles, it is not one of the highlight colors (color or background-color), so paired cascade does not apply.">

            Used values for color and background-color should be the
            UA defaults, usually like black on blue or white on blue,
